Travelling the world looking at the finest men's clothes takes up much of MR PORTER Buying Director Mr Bateman's working life. As such he's well-positioned to draw up a list of this winter's ten best coats. From the formality of Maison Martin Margiela's double-breasted overcoat to the warmth afforded by Canada Goose's citadel parka this is a selection that covers every eventuality, both sartorial and meteorological. As each coat is quite different there would be a certain logic to simply buying every one on Mr Bateman's list, but few men will have enough room in their closet to accommodate such an embarrassment of riches.
